摘要

介绍了碳纤维复合材料（CFRP）的主要特性，阐述了电磁屏蔽原理，通过铝、铝合金、碳钢与碳纤维复合材料的电磁屏蔽对比试验，总结了CFRP作为车体材料时在电磁设计方面应该注意的关键问题，分析了碳纤维复合材料从10×10,3,~40×10,9, Hz频率范围内的电磁屏蔽特性，结合电磁衰减特性曲线对碳纤维复合材料的实际应用提出了建议。

Abstract

The main properties of carbon fiber composites material (CFRP) were introduced, and the principle of electromagnetic shielding was expounded. Electromagnetic shielding characteristics of carbon fiber composite material was studied by electromagnetic shielding test compared with aluminum, aluminum alloy and carbon steel. When CFRP was used as train car body material, some key issues which should be paid attention to were summarized in electromagnetic design, the electromagnetic shielding characteristics of carbon fiber composite materials in the frequency range of 10×10,3,-40×10,9, Hz were analyzed. Some reasonable suggestion was provided for the use of the CFRP electromagnetic characteristic.
